1. Re: what's the best way to travel from Barcelona to Madrid ? Without any doubt, the train is the best way to travel between Madrid and Barcelona. It makes the 620 km (385 miles) that exist between both cities in 2 hours and a half, at speeds up to 300 km/h (186 mph).
Best Answer: Check the RENFE for train services. There's no speed train between Barcelona to Madrid. Right now the Ave train from Madrid ended in Lerida in a 2 1/2 hour trip where you can get another train of approx. one hour to Barcelona. I will not recommended to make that trip unless you spend at least 2 nights in Madrid.
